The speed of road racing is becoming faster and faster, and bicycle development technology is also evolving to meet the needs. The speed of the professional peloton generally exceeds 50 km/h and we live in an era where many riders in the sport run at speeds above 35 km/h.
In a riding environment like this, a bike with high stiffness and light weight as in the past may not always be a good choice. This is because various factors such as weight, stiffness, compliance and aerodynamics must be cleverly integrated to create a more perfect ride.
Swiss bike brand BMC has announced a new racing bike to respond more actively to the changing road riding environment, and it’s the Teammachine R.
Add speed compliance to light pedaling.
The reason why aero bikes and light all-round bikes were initially differentiated was because it was very difficult to combine acceleration for light climbs and speed compliance to maintain speed at high speeds in one bike.
BMC was also responsible for acceleration and speed through its Teammachine do-it-all bike and Timemachine Road aerodynamic racing bike.
However, last season, BMC announced the Team Machine R, which introduced a completely new design, and released a model that meets the performance of an aerodynamic bike even at high speeds while responding uphill with lightness and responsiveness. high pedaling.
Team Machine R provides a light ride uphill and is lightweight and has high stiffness.
On the other hand, it is characterized by the fact that the speed instinct of an aerodynamic bike is still alive.
Collaborate with the Red Bull development team
BMC collaborated with Red Bull Advanced Technology (RBAT), which focuses on Formula 1 racing, to develop the new Team Machine R.
The air resistance of a bicycle is slower than that of a car race, which exceeds 200-300 km per hour, but there are many more complex variables. Because RBAT has a more sophisticated aerodynamic R&D system, it was able to calculate various air resistance variables of the bicycle, and the results of the collaboration between BMC and RBAT were very different from those seen in existing bicycles.
BMC’s Team Machine R, born in this way, showed a different appearance from the shape of existing bicycles, and the riding feel was different not only from existing BMC bicycles but also from existing bicycles.
A completely new interpretation of frame design, abandoning existing bike stereotypes
halo fork
The first impression of the Team Machine R is definitely in the fork. This halo fork, wide left and right and with an angular appearance, focuses on the turbulence that occurs when the rapidly rotating front wheel meets airflow while riding, rather than the air resistance of a stationary bike .
In general, when measuring air resistance with the bike stationary, it is more advantageous to have a narrow, thin fork. However, in cycling practice, strong turbulence occurs due to the rapid rotation of the front wheel, and the air at the point where the fork and head tube meet creates great resistance due to the vortices.
This problem creates resistance not only to the rotational resistance of the wheel but also to the airflow leading to the downtube, so the idea was to change this by widening the fork to allow such turbulence and vortices to flow quickly and cleanly.
The Halo fork quickly relieves turbulence caused by the rapid rotation of the front wheel
Additionally, the head tube is longer and extends rearward and has an aerofoil shape. This shape not only reduces air resistance from the front, but also adds a sailing effect in crosswinds and can also serve to accelerate speed.
As a result, the airflow in the head area, which creates maximum air resistance in the bike frame, became cleaner and, even in real riding tests, the higher the speed, the more stable the speed.
The head tube extends further back to reduce air resistance
It is considered an important element that provides stability and control during high-speed driving.
Mariana bottom bracket design
The bottom bracket (BB) of a bicycle is the center where the down tube and seat tube meet and connect to the chainstay.
Until now, it was common to design bottom bracket shells with the aim of transmitting pedaling power through high stiffness. However, BMC was interested not only in high rigidity but also in air resistance.
Due to the characteristics of bicycles, the air resistance of the low bottom bracket shell is considered important while the cyclist is riding the bicycle. As a result, an integrated design was applied that connects the down tube to the chainstay so that air flows naturally from the down tube to the rear wheel.
Furthermore, an integrated design bottle cage is included as standard, further improving the aerodynamic performance of the lower part of the bike, which is less influenced by the rider.
The design connects the bottom of the downtube to the rear wheel, allowing air to flow faster.
An integrated bottle cage is included as standard to reduce air resistance.
Provides excellent aerodynamic performance from the bottle cage to the bottom bracket and rear wheel.
New seat post clamp
Another noticeable change in the Team Machine R is the shape of the seat post clamp. Existing BMCs have attached clamps to the bottom where the down tube and seat tube meet, but this Team Machine R moves the clamp to the rear of the seat tube, making clamp operation more intuitive.
Seat tube design that falls slightly further back than the seat post and reduces air resistance
A seat post clamp is attached behind the seat tube.
All-in-one ICS carbon aerodynamic integrated cockpit
The ICS cockpit, already introduced via the existing Team Machine, not only has a clean look made from integrated carbon, but also features light weight and a balance of stiffness and compliance.
The new ICS carbon aero handlebar design features a change in handlebar design. The width of the cap and the dropped part of the handlebar were designed to be different, allowing the rider to maintain a more aerodynamic position when holding the cap and perform a stronger sprint when holding the handlebars.
The aerodynamic ICS carbon cockpit has a bonnet width of 360mm and a drop of 420mm.
The new aerodynamic ICS carbon cockpit has a handlebar hood width of 360mm and a drop width of 420mm.
The drop is wider and longer at the back, so it’s very comfortable to hold.

The birth of a new racing bike to represent BMC
The first thing I felt when trying the Team Machine R was a feeling of lightness, different from that of the existing BMC. When climbing a hill at low speed and accelerating slowly, the pedaling response is very light. I felt like I was riding a light and versatile bike.
However, as the speed exceeded 30 km/h, the driving sensation changed. Thanks to the speed adaptability that can be felt in an aero bike, the handling feels calm and stable. Not only was there less weight in increasing speed, but the stable control increased satisfaction.
The change was dynamic, as if riding two bikes at the same time. It looked decidedly different from today’s aero racing bikes, which seem closer to all-around bikes.
The Team Machine R is expected to be a milestone in replacing the BMC generation of racing bikes.
